Dye Tracer Study at the Saginaw Bay, Michigan, Confined Disposal Facility
Abstract
A dye tracer study was performed in August 1987 at the Saginaw Bay, Michigan, dredged material confined disposal facility (CDF). The purpose of the study was to locate the points or areas of outflow or seepage through prepared limestone dikes of the CDF under a variety of wind conditions. The study was conducted to determine whether significant quantities of contaminants were escaping from the site in the seepage through the dikes. The fluorescent dye Rhodamine WT was added to the water in the CDF and allowed to disperse by wind currents. Water samples were collected every 50 ft (15 m) inside and out- side the dikes, and the dye concentrations were measured. Using a mass balance technique, the relative outflow for each 50-ft reach of dike was estimated. Higher seepage rates were determined to exist along the shoreward dike in the deep east side of the south cell of the CDF under all wind conditions.
